Alright so I figured out most of the problem turns out I had a lot of water and my gas from when I removed my bed for painting and all those days exposed to the rains in Florida I managed to drain the whole tank put fresh gas and a few bottles and heet and I cleaned the MAF . I smoked my intake with a fog machine and realized that I had a small vacuum leak at the carbon canister next to the battery so I replaced that hose and now the engine runs significantly better and doesn't stumble when I turn on the AC, the RPMs are still lower with the AC but I guess that's the extra load . Still surging when coming to a stop but I have yet to find that out.
